Off-Vehicle Inspection





1. INSPECT FUEL PUMP RESISTANCE.
- Using an ohmmeter, measure the resistance between the terminals.

Resistance: 0.2 - 3.0 Ohms

- If the resistance is not as specified, replace the fuel pump and/or set plate.





2. INSPECT FUEL PUMP OPERATION.
- Connect the positive (+) lead from the battery to terminal 1 of the connector, and the negative (-) lead to terminal 2.
- Check that the fuel pump operates.

NOTICE:
- These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep the fuel pump as far away from the battery as possible.
- Always do the switching at the battery side.

- If operation is not as specified, replace the fuel pump and/or plate.
